Background technology
For forming the interior shape of the female end of ductile iron pipe, need in the inside of pipe die female end to place core, often pour into a mould a ball graphite cast iron pipe and just need consumption core, between the inner die cavity of pipe die female end and core outside, form the female end of ductile iron pipe.
Be illustrated in figure 1 existing core, the upper end of core is work boss 1 ', the upper surface of work boss 1 ' is provided with circular arc 11 ', is piling up, is carrying in core process, the frequent defect in circular arc 11 ' place of the work boss 1 ' of core upper end, cause the many iron of the female end watering the ductile iron pipe outpoured, cause difficulty to the production of rear line, the spheroidal graphite cast-iron tube faucet quality affecting rhythm of production and produce, the work quantitative change of workman is large, labour intensity uprises, and efficiency reduces.
Be illustrated in figure 2 existing core box; comprise work boss die cavity 3 '; the circular arc 11 ' of the work boss 1 ' of the corresponding core of arc position 31 ' of work boss die cavity 3 '; the top of the circular arc of the work boss of the core upper end of being produced by existing core box does not have boss; protection can not be formed to core upper end working face circular arc; core is being piled up and serious wear in handling process, therefore needs to design a kind of new core box.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, the core of the spheroidal graphite cast-iron tube faucet quality that can ensure to produce, raising workman efficiency; Another technical problem to be solved in the utility model is to provide a kind of core box, can produce above-mentioned core, make core pile up with handling process in can not damage the circular arc of work boss.
The utility model core, comprise work boss, also comprise the annulus boss be connected with work boss one, the center line of described annulus boss overlaps with the center line of work boss, the circular arc that work boss avoided by annulus boss is arranged, the lower surface of described annulus boss is connected to the upper surface of work boss, and the internal diameter of described annulus boss is less than the internal diameter of work boss, and the external diameter of described annulus boss is less than the external diameter of work boss.
The utility model core, the height of wherein said annulus boss is 5mm.
The utility model core, the thickness of wherein said annulus boss is 4-8mm.
The utility model core, wherein said annulus boss is one-body molded with work boss.
The utility model core difference from prior art is that the upper end of the work boss of the utility model core is provided with annulus boss, structure is simple, piling up or carrying in the utility model process, the circular arc place of work boss can not be may wear to, water the spheroidal graphite cast-iron tube faucet outpoured and there will not be many iron phenomenon, the quality of the spheroidal graphite cast-iron tube faucet produced can be ensured, do not affect rhythm of production, to polish underproof spheroidal graphite cast-iron tube faucet without workman, reduce the labour intensity of workman, improve the efficiency of workman.
The utility model core box, comprises work boss die cavity, also comprises the annulus boss die cavity is connected with work boss die cavity one, and described annulus boss die cavity to be positioned at above work boss die cavity and to be communicated with the boss die cavity that works.
The utility model core box, the height of wherein said annulus boss die cavity is 5mm.
The utility model core box difference from prior art is that the utility model core box comprises work boss die cavity, annulus boss die cavity is connected with in the upper end of work boss die cavity, the upper end of the work boss of the core produced by the utility model core box is with annulus boss, piling up, in handling process, wearing and tearing annulus boss and can not may wear to the circular arc of work boss, waters the bellmouth zero defect outpoured.
Below in conjunction with accompanying drawing, core of the present utility model and the core box that manufactures this core are described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of core of the prior art;
Fig. 2 is the structural representation of core box of the prior art;
Fig. 3 is the structural representation of the utility model core;
Fig. 4 is the structural representation of the utility model core box.
Detailed description of the invention
As shown in Figure 3, the annulus boss 2 that the utility model core comprises work boss 1, is connected with work boss 1 one, the setting of annulus boss 2 avoids the circular arc 11 of work boss 1, the circular arc 11 of work boss 1 is positioned at the outside of annulus boss 2, the center line of annulus boss 2 overlaps with the center line of work boss 1, the lower surface of annulus boss 2 is connected to the upper surface of work boss 1, and the internal diameter of annulus boss 2 is less than the internal diameter of work boss 1, and the external diameter of annulus boss 2 is less than the external diameter of work boss 1.
In the utility model, the height of annulus boss 2 is 5mm, and the thickness of annulus boss 2 is 4-8mm, and certainly, the height of annulus boss 2 and thickness can also be other sizes.
Annulus boss 2 of the present utility model is one-body molded with work boss 1.Symmetrical structure centered by the utility model core.
The utility model arranges annulus boss 2 in the upper end of work boss 1, structure is simple, piling up or carrying in the utility model process, circular arc 11 place of work boss 1 can not be may wear to, make to water the spheroidal graphite cast-iron tube faucet outpoured and there will not be many iron phenomenon, the quality of the spheroidal graphite cast-iron tube faucet produced can be ensured, do not affect rhythm of production, to polish underproof spheroidal graphite cast-iron tube faucet without workman, reduce the labour intensity of workman, improve the efficiency of workman.
As shown in Figure 4, the utility model core box comprises work boss die cavity 3, and the annulus boss die cavity 4 to be connected with work boss die cavity 3 one, the lower end of annulus boss die cavity 4 is connected with the upper end of work boss die cavity 3, annulus boss die cavity 4 is communicated with work boss die cavity 3, and the height of annulus boss die cavity 4 is 5mm.Symmetrical structure centered by the utility model core box.
During use, the position of work boss die cavity 3 produces the work boss 1 of core, circular arc 31 position of work boss die cavity 3 produces the circular arc 11 of the work boss 1 of core, when pouring into a mould spheroidal graphite cast-iron tube faucet, the circular arc 11 of work boss 1 upper end is working face, and the position of annulus boss die cavity 4 produces the annulus boss 2 of core.
The non-working surface place car of method on former core box of Vehicle Processing is adopted to go out the annulus boss die cavity 4 that the high ring groove of 5mm can form the utility model core box, the core upper end adopting the utility model core box to make has a circle 5mm high, the annulus boss 2 that 4-8mm is thick, piling up, in handling process, wearing and tearing annulus boss 2 and can not may wear to the circular arc 11 of work boss 1, makes to water the spheroidal graphite cast-iron tube faucet zero defect outpoured.Certainly, the arc groove size of different size can make the size of the annulus boss of the core made different.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
